Correct Answer : Option (A) : first law
Explanation : Faraday’s law of electromagnetic induction states
1. Whenever a changing flux links with a conductor, there will be an EMF induced in the conductor.
2. The magnitude of this induced EMF is directly proportional to the rate of change of flux linkage with respect to time.
These two statements are well-known as Faraday’s first and second law of electromagnetic induction respectively.
